Mechanical Belt Tensioner & Pulley - Main

This unit keeps tension on the main drive belt, which powers the water pump, alternator, and power steering. The bearings in the pulley are known to wear out over time, so we offer this replacement mechanical belt tensioner and pulley kit. From original supplier to BMW, INA.

Description

BMW fitted both mechanical and hydraulic belt tensioners to their models, and the only way to know which one has been fitted to your BMW is with a visual inspection. The belt tensioner keeps the main drive belt tight, ensuring there is enough traction for the water pump and alternator to work. Something as simple as a loose belt can cause a failure of both the cooling and electrical systems. This part has been manufactured by BMW's original equipment supplier INA.

Please note although they are visually identical, this tensioner will not work as a replacement for the air conditioning belt tensioner. The pulleys for the mechanical tensioner are not offered individually. 

Helpful tips

When going about finding a replacement it's best to first determine whether your car has either the mechanical tensioner or the hydraulic tensioner fitted. Ask us about upgrading to the hydraulic tensioner system.
